Early food container aluminum foil mostly uses 3003 aluminum foil. Due to its high cost, they were often used as high-end products and used as disposable food container on airplane.. Later, in order to reduce costs, 8011 alloy also began to be used in aluminum foil tray, but its strength was significantly lower than that of 3003 alloy. It is against this background that Haomei Aluminum has developed 3004 aluminum foil, a low-price, high-strength aluminum foil for food container.
In terms of application, 3004 container foil is widely used in fast food restaurants, takeaway stores, home kitchens, hotels, and service industries related to packaged food. It has outstanding barrier properties and can effectively block gas and moisture to ensure the freshness and taste of food. At the same time, aluminum foil lunch boxes are also hygienic and beautiful, and can maintain heat to a certain extent, meeting the diverse needs of users.
The high strength and lightweight characteristics of 3004 aluminum foil for honeycomb The high strength and lightweight characteristics of 3004. 3003 and 3004 aluminum alloys both belong to the Al-Mn series alloys. Their toughness cannot be increased through heat treatment, but their hardness can be greatly increased through cold working. It is worth noting that both have excellent corrosion resistance and excellent weldability.
Although they belong to the Al-Mn series binary alloys, they are different in composition - 3003 only contains Mn element, while 3004 adds magnesium element on this basis. However, because the solubility of the Mn element in aluminum varies, it is difficult to obtain the ideal reinforcement effect after heat treatment of the 3003 aluminum alloy plate.
Compared with 3003 aluminum, 3004 aluminum alloy has better properties. The special thing is that it has additional magnesium added, which increases the hardness by nearly 10%. 3004 aluminum is popular for its strong texture, excellent toughness and corrosion resistance that is close to that of pure aluminum. In addition, its weldability is also very good, making it easy to carry out various treatments such as softening, hardening or strengthening. Its outstanding pressure processing performance makes it suitable for making various semi-finished products and is widely loved by various industries.
There are some differences between 3003 and 3004 aluminum foil in stock aluminum alloys due to their unique alloy compositions. It is worth noting that heat treatment itself cannot increase hardness, but cold working methods can significantly increase its hardness. In addition, both alloys have excellent corrosion resistance and excellent weldability.
According to the latest survey data, the use of Al-Mn alloy in the can manufacturing and construction industries is gradually increasing. This alloy has excellent bearing capacity and shapeability, and meets stringent requirements such as corrosion resistance and weldability, and is widely praised.
